1. SAFETY
Always locate with proper respect and caution. Equipment misuse or
carelessness can result in serious injury or damage to property. Always follow
safety rules.
HAZARD ALERT INFORMATION
BE AWARE OF SAFETY INFORMATION
This is a safety-alert sign. This is placed in the manual and on
your equipment to alert you to the potential for bodily injury or
death.
SIGNAL WORDS
The safety-alert icon is used with the following signal word :
DANGER, WARNING, AND CAUTION. When you see these
words in the manual or on decals on your equipment, carefully read
and follow all instructions. Watch for these words and learn their
meanings.
DANGER – Imminent hazards which, if not avoided, will result in
death or serious injury.
WARNING – Potentially hazardous situation which, if not avoided,
could result in death or serious injury.
CAUTION – Potentially hazardous situation which, if not avoided,
may result in minor personal injury or property damage.

WARNING
CAUTION
OPERATOR PREPARATIONS
Important : Read and understand this manual before using the Verifier Locator.
Successful use of the Verifier Locator depends on good locating skills and correct
understanding of receiver response.
GENERAL SAFETY
DANGER : Do not attempt to connect to Live Power without proper protective Equipment
and Training.
DAGER ELECTRIC SHOCK : Death or serious injury will result
NOTICE : Do not apply more than 250 volts across clips. More than 250 volts will damage
transmitter.
- 1 -
DANGER : High Voltage. Cutting high voltage cable can cause DEATH or
ELECTROCUTION. Expose lines by a non-destructive means before excavating.
DANGER : Traffic Hazards can result in death or serious injury. Avoid moving Vehicles.
Wear high-visibility clothing.
WARNING : Buried lines. Always confirm your depth estimate by exposing target line by a
non-destructive means.
WARNING : Jobsite Hazards can cause DEATH or SERIOUS INJURY. Wear proper
safety equipment.
NOTICE : Non-metallic lines can be accurately detected only by using a probe.
Remember this before searching and attempting any excavation activity.
NOTICE : Use only alkaline batteries in the Verifier receiver and transmitter.
Batteries contain acid, which may leak if the batteries are allowed to remain in The
equipment when low or completely discharged. This acid can cause Equipment damage.

2. Introduction
Magnetic field
Magnetic field
This equipment is the high performance digital measurement equipment to measure the location and the depth of
buried cable / metal pipe from the ground. By adopting the most recent microcomputer technology, the digital
correction of the measurement data realizes stable and high precious measurement.
- Principle measurement method -
When current flows through a buried cable/pipe, an alternating magnetic field is generated around it.
Location, depth, and current value of the buried pipe can be measured using the Receiver at the surface of the ground.
Signal
Pipe / Cable
Signal
Pipe / Cable
- Feature -
· Adopting differential coil method makes the Receiver to receive the signal from direct below the Receiver by cutting noise from
surrounding area.
· Two kinds of the location measurement mode
*Peak mode: The method to detect maximum sensitivity. High precision.( having error detection protection function)
*Null mode: The method to detect minimum sensitivity point being indicated with arrow. (having error detection protection
function)
No switch operation needed. Applied to at deep depth with stable location work.
· Two kinds of the depth measurement mode
*0-5m (16ft) mode : Measurement of deep depth with high precision is possible at indirect method, the end of cable, and
jointing points.
*0-10m (30ft) mode : Stable measurement is possible at deep depth, near guardrail, or fence.
Do not use this mode with inductive mode.
· The Receiver itself can measure commercial frequency ( 50 / 60Hz, 100 / 120Hz) and Radio ( from 9k to 33kHz) without the use
of the Transmitter.
· The best-suited frequency is automatically selected at radio (9k - 33kHz) with search function.
· The measured data is stored (max. 400 data ) with one-touch operation.
The data can be transmitted to a PC as standard function.
· Broadcasting of four frequencies (512Hz, 9.5kHz, 38kHz, 80kHz) as usage meets various buried pipe.
· A Probe as an option can be used to detect nonmetal pipe.
*The model figure of the differential coil.
The differential coil connected two coils for each other reverse.
